| * Avoid 1 case of holding a semaphore while mmap callbacks are being made.David Smith2009-05-281-57/+75
| | | | | | | | | | | | | | | | | | | | * runtime/task_finder.c (__stp_call_mmap_callbacks_with_addr): Renamed from __stp_call_mmap_callbacks_with_vma(). Also added some code from __stp_utrace_task_finder_target_syscall_exit() that locks the 'mmap_sem' semaphore. This avoids holding the semaphore while the mmap callbacks are made. (__stp_utrace_task_finder_target_syscall_exit): Just calls __stp_call_mmap_callbacks_with_addr() in the mmap case.

| * Suggest rpms to install using debuginfo-install.William Cohen2009-05-2715-66/+985
| | | | | | | | | | | | | | | | | | The patch makes use of the RPM libraries to determine which rpm supplied the executable and from that information suggest a command to install the appropriate debuginfo rpm. This is enabled using the "--with-rpm" option for configure. Can be explicitly disabled with "--without-rpm".
| * Fix nd_syscalls.stp for architectures using SYSCALL_WRAPPERS.Przemyslaw Pawelczyk2009-05-261-305/+568
| | | | | | | | | | | | | | | | | | | | | | | | Add kprobe.function("SyS_*") probe points to nd_syscall.* probe aliases. Analogue of commit 132c337c with two exceptions: - remove sufficiency of these new probe points (use '?' instead of '!'), because translator always considers them resolved, - make non-SyS probe points optional in probe aliases affected by syscall wrappers, because otherwise they will fail on such architectures.

| * Fix another kernel/kprobe.function conflictJosh Stone2009-05-222-7/+8
| | | | | | | | | | | | | | | | | | | | Both kernel.function and kprobe.function were defining a global array stap_unreg_kprobes to use in bulk kprobes unregistration. The compiler allowed the duplicate definition as long as they were the same size, as it was when exercised in buildok/thirtyone. kprobe.function now uses a separate stap_unreg_kprobes2, and the testcase is modified to produce an imbalanced number of probes.
| * PR10190: Suppress warnings for optional kprobesJosh Stone2009-05-222-5/+27
| | | | | | | | | | | | When a kernel.function or kprobe.function fails in registration, we usually print a WARNING and move on. With this patch, kprobes that have the optional '?' flag will not print any WARNING.
| * Move the "pure" tag into the body of __is_user_regsJosh Stone2009-05-222-2/+4
| | | | | | | | | | | | The "/* pure */" tag has no effect unless it is within the embedded-C body of a function. In this instance, they were accidentally moved out during the syscall cleanups.
| * Use embedded-C for empty functionsJosh Stone2009-05-223-12/+6
| | | | | | | | | | | | | | | | | | | | The functions asmlinkage() and fastcall() are used to help access syscall parameters on i686. All other archs don't need this, but they still define empty functions to shield the callers from arch details. However, stap issues warnings for empty script-level functions. This patch changes them to "%{ /* pure */ %}" so there's no complaint, and they will still get optimized away.

| | * Fix gcc warning about Dwarf_Addr initialization.Mark Wielaard2009-05-211-1/+1
| | | | | | | | | | | | * translate.cxx (dump_unwindsyms): Initialize eh_frame to 0, not NULL.
| | * PR10177: init/kill time in sleepy context onlyJosh Stone2009-05-205-44/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, _stp_init_time and _stp_kill_time were being called from begin/end/error probes, which will run with preemption disabled. The BUG reported on RT kernels showed that cpufreq_unregister_notifier can end up sleeping, which violates our preemption block. This patch moves the init/kill into systemtap_module_init/exit, where it is safe to sleep. The code maintains a new predicate with the define STAP_NEED_GETTIMEOFDAY, so we don't still incur any timer overhead if it's not used.
